HIERARCHICAL SOP INSTANCE REFERENCE MACRO ATTRIBUTES

Attribute Name Tag Type Attribute Description
Study Instance UID (0020,000D) 1 Unique identifier for the Study
Referenced Series Sequence (0008,1115) 1 Sequence of Items where each Item includes the Attributes of a Series containing referenced Composite Object(s). One or more Items shall be included in this sequence

Table C.17-3a specifies the Attributes that reference a Series of SOP Instances.

Table C.17-3a

HIERARCHICAL SERIES REFERENCE MACRO ATTRIBUTES

Series Instance UID (0020,000E) 1 Unique identifier of a Series that is part of this Study and contains the referenced Composite Object(s).
Retrieve AE Title (0008,0054) 3 Title of the DICOM Application Entity where the Composite Object(s) may be retrieved on the network.
Retrieve Location UID (0040, E011) 3 Unique identifier of the system where the Composite Object(s) may be retrieved on the network.
Storage Media File-Set ID (0088,0130) 3 The user or implementation specific human readable identifier that identifies the Storage Media on which the Composite Object (s) reside.
Storage Media File-Set UID (0088,0140) 3 Uniquely identifies the Storage Media on which the Composite Object (s) reside.
Referenced SOP Sequence (0008,1199) 1 References to Composite Object SOP Class/SOP Instance pairs that are part of the Study defined by Study Instance UID and the Series defined by Series Instance UID (0020,000E). One or more Items shall be included in this sequence.
>Include ‘SOP Instance Reference Macro' Table 10-11
>Purpose of Reference Code Sequence (0040,A170) 3 Describes the purpose for which the reference is made. One or more Items are permitted in this sequence.
>>Include ‘Code Sequence Macro’ Table 8.8-1 Baseline Context ID may be specified in Macro invocation.
>Referenced Digital Signature Sequence (0400,0402) 3 Sequence of references to Digital Signatures in the referenced SOP Instance. One or more Items are permitted in this sequence. Note: The Attributes in this sequence can be used to detect if the referenced SOP Instance has been altered.
>>Digital Signature UID (0400,0100) 1 The Unique Identifier of a Digital Signature held in the referenced SOP Instance.
>>Signature (0400,0120) 1 The Signature Value identified by the Digital Signature UID within the Referenced SOP Instance UID.
>Referenced SOP Instance MAC Sequence (0400,0403) 3 A MAC Calculation from data in the referenced SOP Instance that can be used as a data integrity check. Only a single Item is permitted in this Sequence. Note: This Attribute may be used in place of the Referenced Digital Signature Sequence Attribute (0400,0402), particularly if the SOP Instance does not have appropriate Digital Signatures that can be referenced.
>>MAC Calculation Transfer Syntax UID (0400,0010) 1 The Transfer Syntax UID used to encode the values of the Data Elements included in the MAC calculation. When computing the MAC, only Transfer Syntaxes that explicitly include the VR and use Little Endian encoding shall be used. Notes: 1. Certain Transfer Syntaxes, particularly those that are used with compressed data, allow the fragmentation of the pixel data to change. If such fragmentation changes, Digital Signatures generated with such Transfer Syntaxes could become invalid. 2. This does not constrain the transfer syntax used to transmit the object.
>>MAC Algorithm (0400,0015) 1 The algorithm used in generating the MAC. Defined Terms: RIPEMD160 MD5 SHA1 SHA256 SHA384 SHA512 Note: Digital Signature Security Profiles (see PS 3.15) may require the use of a restricted subset of these terms.
>>Data Elements Signed (0400,0020) 1 A list of Data Element Tags in the order they appear at the top level of the referenced SOP Instance that identify the Data Elements used in creating the MAC. See Section C.12.1.1.3.1.1.
>>MAC (0400,0404) 1 The MAC generated as described in Section 12.2.1.1, but unencrypted and without inclusion of fields from the Digital Signatures Sequence. See Section C.12.1.1.3.1.2.
